At about 9 a.m., a car pulled alongside a Buick traveling in the southbound lane of North West Street and a man inside the car opened fire, police said.

The driver of the Buick was shot in the thigh, Jackson police said. He was taken to a local hospital with non-life-threatening injuries, police said.

Douglas Baker said he was in the passenger's seat of the Buick when the shooting happened.

"It had stunned me because I thought a car was backfiring until I saw my friend grabbing his side," Baker said. "He hurried up and pulled in the gas station."

Several police officers were investigating Friday morning at the West Express gas station in the 3700 block of North West Street.

"It sounded like two shots and I see two bullet holes on the side of the car," Baker said. "It could have been his little niece on the back seat at the time, because I know he was going to get them later on today."

Police would not release the name of the man who was shot.

Baker said the shooting stemmed from an altercation his friend had a few months ago with the suspected shooter.

"He got the worst end of it and tried to come retaliate with a gun," Baker said of the shooter. "I guess he couldn't take no whooping like a grown man."

Baker said his friend was doing him a favor when the shooting happened.

"All of it could have been avoided," Baker said.

Baker said his friend was taking him to a pawn shop to pick up his shotgun.

"Who would have known what today would have brought?" Baker said. "It just felt like a typical Friday when I got up."

No arrests have been made in connection with the shooting, police said. Anyone with information is asked to call Crime Stoppers at 601-355-TIPS.
